The invention relates to a novel machine for l A further object of the invention is the production of a machine of the character mentioned, the organization of which is such y as to insure accuracy in the filing operation, so that the completed work shall present a nicety of finish comparable to the inish resulting when filing is done by hand. t Furthermore, the invention also has 1n contemplation a filing machine which may y operate on the work both externally and internally thereof. The machine, therefore, is capable of general application within vthe sphere for which it is designed, and is so constructed as to enable the user of the same quickly to adapt the machine for operation on either the exterior or the interior faces of the material presented to the-machine.

Other obj ects and advantages of the invention will become apparent as the nature of the improvements is better understood, the invention consisting substantially in the novel construction, combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and finally pointed out in the appended claims.

The form of the machine which is disclosed herein is a practical-adaptation of the invention, but the latter is capable of embodiment in other forms. Thepresent delineation, therefore, is not to impose restriction on the invention, but 'is to illustrate the incorporation of the inventive concept in such shape as will demonstrate the practicability of the invention for the purposes for which it is in tended.

Referring now in detail to the accompanying drawings, the numeral 10 designates the frame of the machine. It is in the form of a supporting pedestal, the body thereof being curved and terminating at its lower end in a supporting base 11 by which the frame is sustained in applied position to a floor or other surface. The base 11 is provided with a bearing sleeve 12 which receives a driving shaft 13. At one end of said shaft a driving pulley 14 is suitably 'secured thereto over which a belt 15 is trained, and by which power is applied to the shaft 1 from any suitable source. At the opposite end of the shaft 13 there is mounted for rotation with the shaft a driving band wheel 16, the face of whichy is relatively wide.

AAt the top of the frame 10 a pair of spaced guide rods 17 is located. A sliding crosshead 18 is adjustably mounted on said guide rods 17, the movement of said crosshead being controlled by an adjusting screw 19, which screw is threaded into the top portion of the frame 10. This screw is provided with a hand wheel 2O at its lower end for rotating the screw. The upper end of the screw 19 contacts the lower side of the crosshead 18, so

that on rotation of the screw in one direction the crosshead will be moved upwardly, and

. on the reverse rotation of the screw the crosshead will move downwardly.

Hingedly connected with the crosshead 18, as by a suitable pintle 21, is a supporting head 22, which, by reason of thel hinged connection with the crosshead 18, is capable of rocking movement in relation to the crosshead. The Supporting head 22 carries a stub axle 23, said stub axle being txedly connected to the head 22, and mounted for free rotation on said axle 23 is an idler band wheel 24, having a relatively. wide face, and corresponding in Y dimension to the driving band wheel 16. The

wheel 24 is held for rotation on the axle 23 by a securing nut 25.

Extending rearwardly from the cross head 18 is a supporting arm 26 in which is positioned a tensioning bolt 27, the upper end of said bolt 27 passing through the rear end of the supporting head 22. The threaded end of the bolt 27 receives a winged nut 28, and .said nut bears against the head 22 for adjustment purposes. Interposed between the supporting arm 26 and the rear end of the head 22 is a tensioning coil spring 29, the ends of which are received by cupped washers 30 which bear against the arm 26v and the head 22, the expansive force of said spring serving to urge the rear end of the supportin'g head 22 away from the supporting arm 26 against the pressure exerted by the winged nut 28 in its various positions of adjustment.

By adjustment of the tensioning spring 29 under the action of the bolt 27 and its winged nut 28 the relation of the idler band wheel 24 to the driving band wheel 16 is controlled. This control is primarily for the purpose of properly tensioning a flexible belt 31, preferably in the form of an endless steel band or ribbon, which is trained over the wheels 16 and 24. The belt 31 serves as a carrier for a plurality of filing elements 32. By referring to Fig. 7 it will be observed that the ends of the band 31 are provided with interitting perforated ears 33 which receive a connecting pin 34, whereby the ends of the band 31 are secured together. By removal of the pin 34 the ends of the band 31 readily may be separated, the purpose of which presently will appear.

Each of the filing elements 32 constitutes an individual file. They are constructed as files usually are constructed, and their outer faces are scored to provide the necessary teeth requisite for filing purposes.y As seen in Fig. 1, the elements are in vertical alignment when positioned at the vertical stretches of the belt 31.

As the elements pass around the Wheels 16 and 24 they break joint, in order to permit traverse of the belt about these wheels, and after leaving the wheels the elements again the belt, and the breaking of the joints between the several filing elements, each of the latter is' attached to the belt independently of the other elements. That attachment is effected by means of a single screw 35 which pas-ses through a perforation at a point midway the ends of each of the tiling elements.

The head of the screw 35 is countersunk in the exposed face of the filing element so as not to project therefrom. Each of the screws 35 is threaded into an anchoring button 36 which is swaged into fixed relation with the belt 3l, the buttons being suitably spaced apart so as to hold the filing elements in substantial abutting relation with cach other when they are in alignment on said belt. These buttons 36 also are countersunk into the inner faces of the filing elements, so that said inner faces lie flat against the belt 31.

That the tiling elements 32 may be held against 'lateral rocking movement on the belt 31 they are also provided with perforations 37, one of which is placed at each side of the attaching screws 35. These perforations receive guide studs 38 which are swaged into iixed relation with the belt 3l and located one at each side 0f each of the attaching screws. The exposed ends of the studs 38 are rounded, and readily enter and fit the perforations 37. By reason of the construction described, it is evident that each of the filing elements 32 cannot swivel upon the attaching screws 35 and the anchoring buttons 36, and thereby are prevented swerving from parallel relationship with the belt 31. They are always held in proper alignment with the belt to be guided accurately by the latter against the surface of the material which is under treatment.

To support the work in proper relation to the filing elements 32 for action of the latter thereon a table 39 is adjustably mounted on a supporting arm 40 which forms part of the base 11 of the machine. This arm 40 is bifurcated, as clearly appears in Fig. 5, which bifurcation receives a depending flange 41 carried at the lower side of the table 39. The Bange 41 has an arcuate slot 42, and passing through said slot is a fixed guide pin 43 and an adjusting bolt 44, said pin and said bolt being mounted in the supporting arm 40. By reason of the arcuate formation of the slot 42, and the reception thereby of the pin 43 and the bolt 44, the work table 39 may be properly adjusted to the plane of movement of the filing elements 32, thereby insuring proper presentation of the filing action of said elements 32. When adjusted to the desired position the bolt 44 is tightened, and the work table thereby is held in its position of adjustment.

The table 39 has an opening 45 through which the band 31 and the filing elements 32 become aligned. To permit vthis iiexing of pass in the travel of the elements.

adjustment.

Lesern For supporting the filing-elements in rigid relation to the work on the table 39, and to maintain rigidity of each ofthese elements as it crosses the ,face of the work, a plurality of guides is employed. The construction of these guides is illustrated fin detail in Figs. 3, '4 and 5. They arev so disposed with respect to the work table 39v as to position a pair of guides above the table, and'an'other pair thereof below the table. Furthermore, the disposition of the guides `at bot'ligthe upper and under sides of the table issuch as to afford a guide at the front of the filing elements and also one at the rear. Theupper and the lower rear guides are likewise so related that each ling element will over- .lap these rear guides in the passage ofthe .element across the face of the work, and thereby hold the filing element which is iny action on the work rigidly with respect to' the latter, and thus afford a stead cute. ting action of that filing element.

tioned the forward end of the top of the frame 10 is provided witha guide head 46 having a bore 47 of polygonal cross-section,

preferably being hexagonal. This bore receives a vertically-adjustable supporting spindle 48 whichcorresponds in contour to the contour of the bore 47. The spindle 48 is held in different positions of adjustment in the -guide head 46 by a'set screw 49 the inner end of which impingesv against the spindle 48.

The spindle 48 sustains a pair of divergent supporting arms 50 and 51, which arms are adjustably mounted in relation to the spindle 48 by set screws 52, one of which is carried by each of these arms and cooperating with the. spindle 48 to hold the supporting arms 50 and 51 at different positions along the spindle, as occasion may require such The arm 50 carries the front upper guide and the arm 51 the rear VVupper guide. Connected to these respective supporting arms are adjustable supporting blocks 53 and 54, respectively, each of said blocks being held on its supporting arm by a set screw 55. The front upper guide comprises a body member 56 at the opposite sides of which are positioned flange members 57, suitably secured to the body member 56, as by screws 58. The ange members 57 are perforated and receive the trunnions of a series of contact rollers 59, the diameters of which are sufficiently great for the peripheral portions of the rollers to project beyond the edges of the ange members for engagement by the filing elements 32, and thereby provide rolling contacts for these elements as they are guided to the work on the table 39. The front upper guide also includes a verticallyextending attaching shank .60 which is received by a perforation 61 in the supporting member 63 of the upper rear guide.

block 53, in which block the shank 60 is adjustably held by a set screw 62.

The rear upper guide comprises a body member 63, and at opposite sides of this member are positioned flange members 64, riveted or otherwise suitably secured to the body member 63, as at 65. The freev edges of these flange members are turned inwardly. to constitute guide ribs v66, said ribsbeing received by oppositely disposed vertical grooves 67 formed at opposite sides of a vertically-adjustable shoe 68. vBy the engagement of the guide ribs 66 with the grooves 67 the shoe 68 is capable of vertical sliding movement with respect to the body This shoe 68 is held in adjusted position along the body member 63 by a set screw 69 carimpinge against the shoe. The purpose of `this adjustment is to enable the shoe 68 to n the? attainment of the arrangement just menings 7() at spaced intervals throughout its length, said bearings receiving a series of contact rollers 71, said rollers being provided with flanged heads 72 solas to be held against lengthwise displacement from the bearings 70. The contact rollers 71 are also held in the bearings 70 by a keeper plate 73. The

length of this plate is coextensive with the shoe 68, and said plate 73 is provided with a series of transverse slots 74, the edges of which are curved in conformity with the curvature of the rollers 71 so as to permit free. rotation of the rollers in the slots. thickness of the plate 73 is less than the diameter of the rollers 71 so that segments of the rollers project through the slots 74 for contact by the carrier belt 31, and thereby provide a rolling contact for this belt as it passes over the upper rear guide. p

The body member 63 has an upwardlyextending attaching shank 75, and said shank is received by a perforation 76 formed in the supporting block 54 and adjustably held therein at different points by a set screw 77. This set screw permits the bodily ently of the adjustment of the upper rear guide, while the set screw 69 permits the vertical adjustment of the shoe 68 independently of the adjustment of the upper rear guide. Thus, after the bodily adjustment of the upper rear guide to the desired position, it is still possible to adjust the shoe 68 The properly positioned with respect to the Work independently of adjustment of the guide. This is of considerable impo-rtance in order to give rigidity of support to the filing elements 32 ias they pass over the face of the work. The carrier band 31 being flexible, it is obvious that pressure. of the work against the filing elements 32, if the band be unsupported from the rear, will have a tendency to flex the band in a rearward direction, and thus interfere with the proper filing action of these elements. 'With the shoe 68 lowered to the desired point so as to afford a rigid backing for the band 31, it is evident that the band 31 will not yield under pressure of the work, and the filing elements 32 will be held up to the work for proper ling of the same.

The lower rear guide is generally similar in construction to that of the upperrear guide in that it includes a body member 78 having at its front face, and at spaced intervals throughout the length thereof, a series of concave bearings 79. These bearings receive a series of contactrollers 8O which are provided with flanged heads 81 to prevent lengthwise displacement of the rollers from the bearings 79. The rollers 80 are also held from displacement from the bearings 79 by a keeper plate 82 the length of which is coextensive with that of the body member 78. The plate 82 is provided with a series of transverse slots 83, the edges of these slots being curved in conformity with the curvature of the rollers 80 to permit free rotation of the rollers in the slots. The thickness of the plate 82 is less thai the diameter of the rollers 80, so that seg ents of these rollers project through the slots 83, similar to the rollers 71, forcontact by the carrier belt 31. This provides a rolling contact for said belt 31 as it passes over the lower rear guide.

The keeper plates 73 and 82 are detachably held on the shoe68 and the body member 78, respectively, by 'screws 84, or their equivalent. This permits ready displacement of the keeper plates, and removal of the rollers 71 and 8O or replacement thereof should such be necessary. l

The lower rear guide is carried by an L- shaped supporting bracket 85. This bracket is mounted on one face of the supporting arm 40, being held in position thereon by a pair of screws 86 received by a pair of elongated slots 87 formed in the body of the bracket 85, the screws being threaded into said supporting arm 40. The provision of the slots 87 enables adjustment of the bracket 85 in the lengthwise direction thereof, and this permits the lower rear guide to be adjusted towards or away from the carrier belt 31 and the filing elements 32 mounted thereon. The immediate connection of the body member 78 of the lower rear guide is through a pair of screws 88 which engage said body member 78 and are received by a pair of slots 89 formed in the footportion of the supporting bracket 85. The screws 88 and slots 89 permit adjustment of the lower rear guide c'rosswise of the belt 31, and insure proper positioning of the guide so that the flanged heads 81 of the rollers 80 may embrace the side edges of said band.

The lower front guide partakes generally of the construction of the upper front guide. 1t includes a body member 90 at the opposite sides of which .are positioned flange members 91. These are suitably secured to the body member 90, as by screws 92. The members 91 are perforated and receive the trunnions of a series of contact rollers 93,. The diameters of these rollers are sufficiently great for the peripheral portions thereof to project beyond the edges of the flange members 91 for engagement by the filing elements 32, thus providing rolling contacts for these elements as they lare guided away from the work in passing downwardly through the opening 45 of the table 39. The lower front guide is carried by an L-shaped supporting bracket 94. This bracket 94 is mounted on the supporting bracket 85 by a pair of bolts 95, said bolts being received by the slots 87. The bolts 95 and the slots 87 permit adjustment of the supporting bracket 94 towards and away from' the carrier belt 31 and the filing elements 32 thereon, thus adapting the lower front guide for proper presentation to the filing elements to guide the same as they pass from the work.

The immediate connection of the lower front guide with the L-shaped bracket 94 is effected by a pair of bolts 96. These bolts are threaded into the body member 90 of said guide and are received by a pair of vertically-elongated slots 97 formed in the foot of the bracket 94. These bolts and slots permit slight vertical adjustment of the lower front guide towards and away from the table 3 9.

The foregoing description hasin contemplation the use of the elements 32 as files, thus effecting by mechanical power that which generally is done by hand. It is. clearly within the purview of the invention to substitute for the filing elements 32 other instrumentalities designed for abrasive and buiing purposes. In Figs. 8 to 13 inclusive are illustrated such instrumentalities.

As instancing the use of an abrasive element, the invention has in view that construction illustrated in Figs. 8, 9, and 10. This includes a shoe 98 having an attaching rib 99f.for1iied at one face thereof provided with under-eut edges 100. About this attaching rib 99 a body of abrasive grits 101 is molded. Preferably, these grits are carborundum or the like. The abrasive grits` therefore, may be utilized, for abrasive purposes, as distinguished from filing.

As instancing the use of a buliing element, the invention may employ that construction illustrated in Figs. 11, 12 and 13. This ini cludes a metallic shoe 102. Suitably connected thereto. is a hardened fiber facing 103, and cemented to said facing 103, or otherwise suitably connected thereto, is a layer of felt 104, or other suitable material of a yielding nature, and of such character as to permit a facing of emery grits 1057 or other suitable material, to be applied thereto, as by clementing. As distinguished from the abrasive grits illustrated and described in connection with it is essential for the filing to be done at the interior as well as the exterior of the work. When required for interior filing, it will be understood that the tensioning action of the idler band wheel 24 is released by proper manipulation of the bolt 27 and its controlling Wingnut 28. This flexes the carrier belt 31 sufiiciently to permit the ends thereof to be disconnected by the removal of the pin 34 from the interfitting ears 33. With the ends thus separated one of the same is threaded through lthe opening of the work, thus positioning the carrier belt and the filing elements at the interior of the work. The ends of the carrier belt4 are then connected and the belt again placed funder tension by proper adjustment of the idler band wheel 24 in relation tothe driving band wheel 16. As the thickness or height of the work on the table 39 will vary from time to time, it

is necessary to adjust the upper guides so as properly to position the same with respect to the work, and thus to insure rigidity of the filing elements as they'pass across the face of the work. The primary adjustment in this respect is effected by releasing the set screws 62 and 77 and moving the attaching Shanks and 75 of the guides vertically in the supporting blocks 53 and 54 to the required positions. After tightening the lset screws 62 and 77 the shoe 68 is then adjusted towards the table 39 so as to lower it as near as possible to the table and position the lower end thereof in such proximity to the work, or to the table, as wil insure a rigid backing or supportfor the carrier belt 31 and the filing elements 32 as the latter pass across the face of the work. If the work is not positioned immediately in the downward path of movement of the shoe 68, the latter may be lowered into the opening 45 and into contactwith the upper end of the lower rear guide. In that event a dowel stud 106 willenter a recess or socket 107 formed in the lower end of the shoe 68, and thereby effect a rigid relation between themeeting ends of the upper and lower rear guides. The machine nowy being set in operation, the filing elements 32 pass rapidly across the face of the work. cutting vaway the vface in the characteristic manner of the action of files. When the work is completed, detachment vof the ends of the carrier belt 31 will permit the die to be removed from the carrier belt and the work table.

When. .the filing toperation is being performed on the exterior of the die or other work presented to the filing elements, the shoe 68 is positioned with respect to the work and the table 39 in a manner which is obvious from the above description. This positioning of the shoe 68 establishes the proper rigid support for the filing' elements, and in pressing the work against the filing elements the belt 31 is prevented flexing and the filing elements are held rigidly to the work.

In the positioning of the shoe 68, it will be understood that it is moved to such a point towards Athe table 39 that with the lower endl of each filing element 32 positioned between the lower' front and rear guides the upper end of said element will overlap and be supported by the shoe 68. In that position of the flling element the greatest resistance is offered thereby to the pressure of the work as the latter is presented to the filing element for action by the latter on the work. The filing element, therefore, is braced at its upper and lower ends, and its accurate cutting action thereby assured.

In the traverse of the carrier belt 31 and the filing elements32 over the rollers 71 and 80, of the upper and lower rear guides, the flanged heads 72 and 81 of these rollers embrace the carrier belt and the filing elements, and thus prevent crosswise movement or swervingrof the same in relation to the work under treatment. These flanged heads thus effectually guide the carrier belt in its travel.
